You’ve landed here because you know nutrition and training matter. You just want a system that actually makes sense — and that you can own for life.
Premium health performance coaching for ambitious professionals who are done trading their wellbeing for their career.
Hi, I'm Sim.
I'm a qualified fitness coach and natural Pro Athlete in the ICN Bodybuilding Federation — and I still work full-time as an Executive Assistant alongside running Longevity by Design.
I know firsthand what it's like to pour everything into your career while your health quietly slips down the priority list. I've also been through injury, surgeries, and rebuilding from scratch — all the way to competing on a professional stage. That journey taught me one thing: the right system, followed consistently, produces results every time.
That's what I coach from. Not a textbook. Not a trend. Lived experience — and a Certificate III & IV in Fitness to back it up.
I work with a small number of clients at a time so every program is genuinely personalised.
